HORIZONTAL HOT PRESS TRANSMISSION/DRIVE SYSTEM ASSEMBLY
MANUFACTURABILITY STUDY and REDESIGN FOR MANUFACTURE
Project Goal:
To assess the manufacturability of the current design, based on the included drawing package, under production conditions.The drawing package details a transmission/drive system for a horizontal hot press capable of 250ºF and 10,000 lbf per drive unit. Four serapid chain drives are used to power the heated platen. (These are drives that push a chain without chain buckling.) Load cells in series with each chain are used in control of the system. The structural framework supports four serapid drive units (~45 lb each) and is the reaction point for the platen loads. Outboard of the transmission drive framework is the reducer/motor mounting plate.
Approach:
Based on existing design information,review the proposed manufacturing techniques assuming a production volume of 1,000 units/year.Recommend specific manufacturing methods that are most appropriate for component production within the present design. Also, develop an approach to component redesign aimed at most efficient manufacture.Parameters for design optimization for manufacture are to include:
Production Cost Decrease,
Assembly Ease,
Lifetime Cost Decrease (maintainability)
Reliability Improvement
Manufacturing Study
Perform a critical review of existing design drawings. Discuss the present level of manufacturability (on a part-by-part basis if necessary). Describe changes that could be made to improve manufacturability without engaging in major hardware redesign.
Determine components within the existing design that will benefit most from manufacturing method/materials changes based on estimated cost to manufacture, as well as on the optimization parameters defined above. Make recommendations regarding how you believe the manufacturing methods and materials should be modified for the determined high payoff components, on a component-by-component basis.
Design for Manufacture
Initiate a redesign for manufacture based on existing design drawing. (Redesign will be constrained by the need to interface directly to all other modules of complete unit.)[This is meant to be a design for manufacture study, not a mechanical design report!]
What should I look at to achieve the above criteria.
